Travel bag

ABSTRACT

A travel bag is disclosed having a wheeled foldaway support pivoted to the back side of the wheeled bag thereof and coupled to the bottom end of the retractable handle thereof through links such that when the retractable handle is pulled out of the wheeled bag, the wheeled foldaway support is turned outwards from the back side of the wheeled bag for supporting the wheeled bag on the floor in a tilted position.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to travel bags and more particularly to atravel bag with a wheeled foldaway support.

2. Description of the Related Art

A regular wheeled travel bag generally comprises a bag for holdingthings, a plurality of wheels pivotally mounted on the bottom side ofthe bag to make it easy to move, and a retractable handle mounted in theback side of the bag and alternatively set between a retracted positionand an extended position. When in use, the retractable handle is set inthe extended position so that the user can carry the extendedretractable handle to drag the travel on the floor in a tilted position.

When the user is dragging the travel bag on the floor in the tiltedposition, the user's hand and the wheels support the weight of thewheeled travel bag and its stored items. Because the user's hand bearsmuch pressure from the load when moving the wheeled travel bag, theuser's hand will ache soon.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances inview. It is the main object of the present invention to provide a travelbag, which is equipped with a wheeled foldaway support so that the usercan drag the travel bag stably on the floor with less effort.

To achieve this and other objects of the present invention, the travelbag comprises a bag, wheels, a retractable handle, and a wheeledfoldaway support. The bag has a top side, a bottom side, and a backside. The wheels are pivotally mounted on the bottom side of the bag.The retractable handle is mounted in the back side of the bag andalternatively set between an extended position and a retracted position.The foldaway support is pivotally mounted on the back side of the bagand coupled to the retractable handle. The foldaway support comprises asupporting frame, which has a fixed end pivoted to the back side of thebag and a free end opposite to the fixed end, at least one rollerrespectively pivotally mounted on the free end of the supporting frame,and at least one link each having a first end pivotally coupled to thebottom end of the retractable handle and a second end pivotally coupledto a part of the supporting frame. Therefore, when the user pulls theretractable handle out of the bag from the retracted position to theextended position, the links are forced by the retractable handle topush the supporting frame outwards from the back side of the bag to theextended position for supporting the bag on the ground in a tiltedposition.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic drawing showing a travel bag in operationaccording to the present invention.

FIG. 2 is a schematic side view of the present invention, showing theretractable handle and the foldaway support extended out.

FIG. 3 is another schematic side view of the present invention, showingthe retracted status of the retractable handle and the foldaway support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1˜3, a travel bag in accordance with the presentinvention is shown comprising a bag 1, a retractable handle 2, aplurality of wheels 3, and a foldaway support 4.

The bag 1 defines therein an accommodation space for holding things,having a receiving hole 11 vertically extending to the top side thereof.

The retractable handle 2 is mounted in the vertically extendingreceiving hole 11 of the bag 1 and alternatively set between an extendedposition and a retracted position.

The wheels 3 are pivotally mounted on the bottom side of the bag 1 tomake the bag 1 easy to move.

The foldaway support 4 comprises a pair of rollers 43, a supportingframe 41, which has a fixed end pivotally coupled to a first pivot joint51 at the back side of the bag 1 and a free end mounted with the rollers43, and two links 42, each of which is inserted through a respectivelongitudinal sliding slot 12 on the back side of the bag 1, and has afirst end respectively pivotally coupled to a second pivot joint 52 atthe bottom end of the retractable handle 2 and a second end respectivelypivoted to a part of the supporting frame 41 between the fixed end andfree end of the supporting frame 41.

When the retractable handle 2 is pulled to the extended position, thesecond pivot joint 52 is moved toward the first pivot joint 51, and thelinks 42 are forced to bias the supporting frame 41, and therefore thesupporting frame 41 is turned outwards from the back side of the bag 1to an extended position where the supporting frame 41 defines with theback side of the bag 1 a contained angle. At this time, the wheels 3 andthe rollers 43 support the travel bag on the ground in a tiltedposition, and the user can drag the tilted travel bag on the groundstably with less effort.

When not in use, the travel bag is kept on the ground in vertical, andthen the retractable handle 2 is pushed back from the extended positionto the retracted position to move the second joint 52 downwardly awayfrom the first joint 51, and therefore the links 42 and the supportingframe 41 are received together and closely attached to the back side ofthe bag 1 (see FIG. 3).

A prototype of travel bag has been constructed with the features ofFIGS. 1˜3. The travel bag functions smoothly to provide all of thefeatures discussed earlier.

Although a particular embodiment of the invention has been described indetail for purposes of illustration, various modifications andenhancements may be made without departing from the spirit and scope ofthe invention.
